MC74AC157, MC74ACT157 Quad 2Input Multiplexer The MC74AC157/74ACT157 is a highspeed quad 2input multiplexer. Four bits of data from two sources can be selected using the common Select and Enable inputs. The four outputs present the selected data in the true (noninverted) form. The MC74AC157/74ACT157 can also be used as a function generator.
